Function:
This output activates a relay switch.
Relay outputs 6/7/8/9 can be used for showing status
and warnings. The relay is activated when the condi-
tions for the relevant data values have been fulfilled.
Activation/deactivation can be programmed in param-
eters 701/704/707/710 Relay 6/7/8/9, ON delay and
parameters 702/705/708/711 Relay 6/7/8/ 9, OFF de-
lay.
